Help with any of these chemistry problems.?

Question

Determine the type of reaction and write a balanced chemical equation for each of the following:

i) Sulfuric acid is combined with solid magnesium hydroxide.

j) Solid barium oxide is added to distilled water.

k) Isopropyl alcohol (C3H7OH) is burned in air.

l) Iron metal shavings are added to hydrochloric acid.

m) Solid sodium carbonate is heated in a crucible.

n) Solid aluminum hydroxide is added to perchloric acid.

o) Sodium metal is added to distilled water.

Answer 1

i) is a neutralisation reaction (base + acid)

   H2SO4 + Mg(OH)2 -> MgSO4 + 2H2O

ii) Dissolution

   BaO -> Ba 2+ ions and O2- ions. You can put the water in but it is usually taken out.

iii) Combustion reaction

   C3H7OH + O2 -> H20 + CO2

iv) Forgot the name

   Fe + 2HCl -> H2 + FeCl2  that is if the iron is Fe(II)

soz but i've got to go lol...you can check them on some good chem sites.

Answer 2

The above response did not include all of the information that need nor did it provide the basics that you need for an understanding.  Here are detail explantions of the reactions.

1) 1 H2SO4 + 1 Mg(OH)2 --> 1 MgSO4 +  2 H2O  Double Replacement reaction

2) 1 BaO + 1 H2O --> 1 Ba(OH)2 - synthesis reaction

3) 3 C3H7OH + 13/2 O2 --> 9 CO2 + 11 H2O Combustion reaction

4a.) 2 Fe + 6 HCl --> 2 FeCl3 + 3 H2

(Fe3+) - Single Replacement reaction

4b.) 1 Fe + 2 HCl --> 1 FeCl2 + 1 H2

(Fe2+) - Single Replacement reaction

Note: Fe ion is a transitional metal and has two oxidation numbers. You didn't specify the charges (oxidation numbers), so it has to be Fe2+ or Fe3+.  I will balance both of the reactions but you have to figure out the type of reaction.

5) 1 Na2CO3 --> 1 Na2O + 1 CO2 - Decomposition reaction

6) 1 Al(OH)3 +3 HClO4 -->1 Al(ClO4)3 + 3 H2O - Double Replacement reaction

7) 2 Na + 1 H2O -->1 Na2O + 1 H2  - Single Replacement reaction

I hope this explanation will help!
